Test Background
Fiber-reinforced plastic tensile test can determine the short-beam method interlaminar shear strength of thermosetting or thermoplastic fiber-reinforced plastics that are subject to interlaminar shear failure.
Zhongke Testing Reliability Experiment Center has reliability testing capabilities for various fiber-reinforced plastics and provides professional interlaminar shear testing services for fiber-reinforced plastics.
Scope of tests
Commonly used fiber-reinforced plastics include polypropylene (PP), polyethylene (PE), polyester (PET) and other high-molecular polymers and high-purity natural wood, as well as some man-made fibers (cellulose fibers), glass-reinforced resins and metal fibers.
It can be divided into three categories according to its molding methods: thermoplastic resin, thermosetting resin, and polycarbonate.
Test method
1. Use a rod with a rectangular cross-section as a simply supported beam, place the rod on two supports, and apply a bending load at the center of the supports to cause interlaminar shear failure.
2. Failure mode records the failure mode according to the following categories:
a) Acceptable interlayer shear failure modes: single layer shear, multiple shear
b) Unacceptable failure mode:
Mixed failure modes: shear and tension, shear and compression
No shear failure modes: tension, compression;
Plastic shear.
